Ground vibration monitoring for construction blasting in urban areas

This study addresses the need to update the California Department of Transportation (Caltrans) standards related to vibration monitoring programs and equipment, acceptable tolerances for vibrations for various classes of urban structures, and the recommended limits for pre-blast damage surveys. The area confined within a pre-construction and post-construction survey covers a region in which vibrations have the potential to cause structural damage as well as perceived damage from residents. The study first discusses the origin of Caltrans vibration specifications. Instrumentation used in the study is described. Actual field vibrations from 27 rock blasts which occurred on the Route 54 project in San Diego county, with observations recorded for vibration measurements, are documented. The study concludes that future research into setting pre-blast survey radius limits is justified, as this would lead to considerable savings.
